MACHINE FOR APPLYING METALLIC LEAF.

Specification of Letters Patent.

Patented Apr. 2, 1918.

Application filed December 5, 1916. Serial No. 135,159.

To all whom it may concern:

Be it known that I, Anne BRooKn, a subject of the King of Great Britain,residing at Glasgow, Scotland, have invented certain new and usefulImprovements Relating to Machines for Applying Metallic Leaf, of whichthe following is a specification,

The present invention, which relates to machines for applying metallicleaf, has reference to improved means for automatically lifting, and(or) transferring and pressing the metallic leaf for ornamentation orother purposes, and is an improvement upon my prior United Statesinvention, Patent No. 1,162,448 issued November 30th, 1915.

In the specification of my prior patent I described a machine into whichthe leaf was automatically fed and in which the necessary lifting,transferring, and pressing operations were automatically performed bymeans of an oscillating or reciprocating device which alternated betweenthe leaf and the book or other article to be im pressed.

The present invention consists in providing a. device which is adaptedto carry the metallic leaf and the article to be operated on and movethem alternately under an impressing device or die, which may be fixedor movable, and which serves both to lift or transfer the leaf and applyit to the article, these operations being automatically performed.

Means, automatically actuated, and substantially described in my saidprior specification, may be used to sever portions of the leaf, and samemay be placed at any convenient position between the reels of leaf andthe feeding mechanism.

The usual greasing device may also be incorporated with the mechanism toinsure that the leaf adheres to the lifting device.

In order that the invention may be clearly understood I have hereuntoappended explanatory drawings whereon I have shown, by way ofillustration or example, a preferred mode of carrying the invention intoeffect or practice.

On the drawings Figure l is a front elevation of such parts only of themachine as are necessary to explain this invention.

Fig. 2 is a corresponding side elevation.

Fig. 3 is a corresponding plan.

Figs. 4 to 9 are detail views.

The arrangement shown comprises an impressing devlce C and a travelingcarriage which is moved backward and forward underneath the impressingdevice by means of suitable mechanism. The carriage has, on it, twotables, one marked 0 upon which the article to be treated is placed andwhich may be of substantially the same construction as the tabledescribed in the specification of my prior U. S. Patent No. 1,162,448and a second table 6 over which the leaf is fed. The carriage, which ismarked 6 carries also the severing knife 7" and its mechanism, the reelsor spools of metallic leaf, and the pulling or feeding device; the knifemechanism, and the spools being arranged on a bracket a at the righthand side of the carriage, Fig. 1, and the pulling or feeding device Dbeing arranged on an extension 6'' at the left hand side of thecarriage. The knife and its mechanism may be substan tially the same asthat set forth in the specification No. 1,162,448 while the pulling orfeeding device may be of essentially the same construction as that setforth in the specification of my co-pending application Serial No. 92137filed April 19th, 1916.

There may be one or more spools of leaf according to the work to be doneand the spool, or spools, is, or are, arranged in the receiver a fittedon the bracket a a shows one of the spools.

The carriage c has rollers e which run upon the surface 1 of the bed Bof the machine and this carriage is reeiprocated by means of a rack 71,shown in dotted lines in Fig. 2, which is operated by means of a toothedquadrant i fixed to a shaft j which in its turn, is operated by a pinionj under the action of a rack is connected to a grooved cam Z shown inthe detail views, Figs. 7 and 8. In the groove Z of this cam works a pinm projecting from the side of a disk at on the main shaft n which latteris, preferably, driven b a belt pulley E and driven belt I. On t 1eshaft n is a second cam 0 having a groove 0 in which works a pin p on avertical rod 5 This rod 9 is moved upward and downward in guides g andit operates, through a link f, a toothed sector 9" pivotally mounted ona pin 1' of the frame A. The teeth of this sector mesh with the teeth ofa similar sector also marked 1' and also pivotally mounted on a pin r ofthe frame A and the sectors are adapted to operate links 8. a. so as toraise and lower the impressing device which is guided in its verticalmovements by a guide rod 6 working through a guide way in the frame iNow. it is obvious. that. when the shaft It is rotated the cam I will hecaused to move backward. and forward thereby reciprocating the rack Aand turning the pinion i and quadrant I so as to reciprocate thecarriage e and move the tables 6 and 0 alten nately underneath the dieblock 2* of the impressing device and these movements of the carriageare arranged so as to properly synchronize with the vertical moven'ientsof the die block, the cams Z and 0 being groin ed to give the desiredmovements at the proper times and in the proper sequence.

The operating wheel D of the dcvit't' ii for pulling the paper strip orstrips so as to feed the leaf is operated by a long pinion D which isdriven by means of shafts 3). i, 3 and gears 6, T. 8. 9, from the mainshaft ii. The pinion D is of such length as permits of the full travelof the carriage without the wheel D getting out of gear.

From the shaft 10 of the wheel T) the severing knife is driven by meansof gears 12, shafts 13, 14, and face cam .r. 'l he severing mechanism isshown at Figs-z. i and 5 and, as will he seen, it is similar to thatdescribed in my prior specification No. 1,162,448 except that the knife7" has actuating rod operated by the face cam a). f is a roller overwhich the strips with the metallic leaf pass, under the knife f. andthen over the table a to the pulling device D. There may he any desiredmun-- its her of strips used. the rolls for the strips being simplyinserted into the receiver frame a fixed on the bracket (4 This framehas grooves 1.5 in its sides and each roll of leaf is secured to a plate16 which is then dropped into one pair of grooves l-i so that the rollappears as at Fig. 3 which is a plan view of part of the frame whichlatter also shown in vertical section at Fig. i. To separate the rollsfrom one another partition plates. as at lT. Fig. i are used and droppedinto the grooves 15. In the machine I have only shown two strips of leaf18. 19, with two winding spools for taking up the paper strips. thesespools being indicated at 20, 21. Fig. 1.

The arrangement is. preferably. such that when the table 6 is under theimpressing device the latter first descends. contact with, and thenlifts up the severed piece. or pieces. of leaf on the table 0" and whichit is desired to apply to the article. To do this. at the next forwardmovement of the carriage, the table 6 is moved froi'n under theimpressing device while the table 0 is brought under the impressingdevice whereupon the latter descends and applies the leaf to the articleon the table.

In the arrangement hovvn the article to be treated is placed upon thetable c by hand but it may he mechanicall fed thereto in any well knownand usual manner, the table being constructed and arranged accordingly.

The cam I. \vhlch is shown in detail at Figs. T and S, has its groove Zof a peculiar shape. the groove being curved at the sides Z Z andstraight at the parts F, The circle m Fig. 7. indicates the path of thepin m. of the dish m and the pin. as it travels this patl'i. moves thecam, when it is in the part. Z toward the left and. when it is in thepart I". toward the right. hen the pin traverses the curved groove Z thecam is held stationary and consequently the carriage is statioi'iary andthus a pause takes place. during the lifting of the leaf from the table6 by the die 0, and, when the pin travels the longer curve 1 theearriage is again caused to pause, and this pause takes place when thetable 0 is under the die L and the gold leaf is being pressed andblocked upon the article. The reciprocatory action of the cam Z issufficient to cause the quadrant i' to move the table first toward theright hand. Fig. 2. and from underneath the impressing device. at thesame time simultaneously moving the table 0 under the said device. and.then. at the next return movement. to shift the table 1." from under theimpressing device and bring the table (1 thereunder. the table 0" andthe table 0 being, in this manner. brought alternately underneath theimpressing device. It is necessary when the tables are underneath theimpressing device and the latter is acting upon the leaf or the article,as the case may be. tha the carriage should be held stationary for amomentary period and this is effected as before stated by the action ofthe pin "m and the cam grooves Z Z Likewise. it is necessary during theblocking operation that. the aticie should remain in contact with the.article for a short period and this eifreted by the action of the cam 0whose groove o it will be noticed, Fig. 2, is flattened at its upperpart so as to produce the necessary pause in the movement of the die While the article is being impressed and blocked the pulling mechanism Dcomes into operation and effects a feeding movement of the metallic leafso as to bring a new piece, or pieces, of leaf upon the table in orderto be. transferred by the impressing device to the next article.

The severing device f is arranged to act properly in conjunction withthe pulling device D this being effected in the manner set forth in mysaid U. S. specificat ion'Sei-ial No. 92137.

The die block 1 of the impressing device, (7 is greased automaticallyll) means of a greasing roller u shown at Fig. '3 and also to anenlarged scale at Fig. 9. This roller is mounted on the upper end of arod u carried in brackets 11 u. on the rack 11. A spring It acts toforce up the rod u and the extent of the upward movement can heregulated by means of the screw out f. livoted on the bracket u" is acatch :1" wh'ch has a downward extension u weighted at N". Ah thecarriage travels toward the right hand Fig. 9. the rod u eventuallymeets a pin a in a bracket 11* on the frame A and strikes thereagainstcausing the catch a to swing and disengage the pin of the roller u.whereupon the greasing roller springs upward so as to contact with theunderside of the die block 1 and. as the carriage moves along; greasethe die hlcelc. When the rod 1/ is free from the pin u it actsautomatically to catch the roller u again, while the latter is forceddown bv the die block 1.. and hold it in the position shown at F ig. 9.

It is obvious thedetails of construction of the various parts of themechanism can be altered or modified without departing from theinvention.
